The antenna is another weak point in some cases.? Most antennas? that have traps or some chokes in them will not handle the near 100 % duty for very long periods .? My OCF will not handle the full

Thanks Steve!? I wonder who figured out the crystal baking trick?!?!

I don't think anyone is suggesting 1200 watts on FT8 from a Drake amp. My suggestion was more like around half of that at the most. I have a couple of Alphas that would do that but my antenna would

Hi Jim: Can you tell me who is selling those modification kits? 73s Wolfgang dk7cy

My first suspect with a “one bad band” rig, after verifying all the switch contacts, is the band crystal. They are now of the age where their failure rate is significant. If the swapped crystal

I Had to rebuild the power supply and get more than 800 watts output. 73s Wolfgang dk7cy

Thanks, I will give that a try!

All 7-Line and 4-Line filters are 50 ohms. Roofing filters are different. Rob, NC0B

I got a couple of Drake SL-2300 2.3-5645kHz Filters at a swap meet and am contemplating testing them with a NanoVNA.? I have three concerns. 1) Can I directly connect the filter to the Nano VNA? I am

I thought I posted this but will try again. My T4X-B just stopped transmitting on 75 and 160. Not sure if 160 worked before since I never tried it, but losing 75 meters is hard since that is my major

I would not suggest running 1290 watts out on FT-8, on 80m anytime soon. ( I get 1290 watts PO into a DL, using 3 x calibrated meters, bird, coaxial dynamics and also an array solutions

Thanks Glenn, I'll continue investigating, check a handful of other resistors but no dice.. Thanks, Michael.

I agree. Selling on eBay is not a walk in the park these days. I've run into sellers at hamfests who said they stopped selling on eBay because it became to much of a PITA. No one is getting rich

Hi Michael There are more AGC/s-meter information in this group: /g/DRAKE-RADIO/search?q=R-4B+AGC /g/DRAKE-RADIO/search?q=R-4B+s-meter -- best regards, Glenn, OZ1HFT

As I recall, the L75 had more than half the output of the L7. ?Even though the L75 only had one tube, it had a higher plate voltage than the L7 and thus the resulting power out. 73, Evan, K9SQG

I am not addressing Stan directly, but I think a comment here is useful. As an eBay seller for 25 years, I take exception to the term “epay” to describe sales on this valuable resource for finding

Thanks. I found some 201 series pots on Epay, but the price for 2 is what I gave for a 10 piece of the horizontal mount 201 series pot. The R-4B receiver sensitivity and S meter sensitivity pots are
